Buzzing anticipation. Floating weightlessness. Adrenaline rush. All the best feelings wrapped into an emotional high that never gets old. I think I might be addicted to falling in love. When rising rock star Jack Kingston comes to play on our college campus, I think he’ll be just another fix. Instead, he flips everything around and makes me question who I am, what I want, and why I do what I do. After he leaves, everything changes. Pushing myself in the pool, struggling to keep up with my twin sister, it’s what keeps me from losing myself entirely. Swimming isn’t my passion. It’s my source of stability. When I find the courage to finally start pushing my boundaries, I discover success in ways I never imagined, both in and out of the water. When Jack resurfaces, I'm forced to decide between facing my fears or letting them spiral out of control as my past catches up with me... threatening to pull me back under. It's time to sink or swim. *This is the second book in the Spark Sisters series but can be read as a standalone novel.*
